arachnoid cysts/asthenia

A 7-year-old male admitted with neck rigidity, severe pain in the abdomen, and progressive weakness in the lower limbs was diagnosed as having a spinal intramedullary arachnoid cyst. There was a dramatic and immediate recovery after fenestration of the cyst.

A 49-year-old woman developed slowly progressive muscle weakness of the right upper and lower limbs. Physical examination revealed exaggeration of deep tendon reflexes in bilateral lower extremities and a Th5-Th6 girdle sensation. Weakness in her right upper extremity suggested cervical or

BACKGROUND Lumbar intradural arachnoid cyst (AC) concomitant with hyperacute spinal subdural hematoma (SSDH) has never been reported in the literature. OBJECTIVE To report a case of lumbar AC superimposed by hyperacute SSDH, which was difficult to diagnose preoperatively using magnetic resonance

Anterior thoracic intradural arachnoid cysts (ATIACs) are a rare cause of spinal cord and nerve root compression, for which different treatment strategies have been proposed. Although ATIAC represents a well-known clinical entity, the choice of surgical method has not been uniform, and no study has

The reported incidence of clinically significant arachnoiditis following oil-based contrast media myelography is approximately 1%. The incidence of arachnoiditis in the dorsal spine is even more rare. Acquired arachnoid cyst formation can occur with arachnoiditis of various aetiologies. A case is

OBJECTIVE Preoperative magnetic resonance imaging (MRI) myelography scans demonstrated a dural defect in a 50-year-old man with an epidural arachnoid cyst who had a 29-year history of untreated weakness and numbness both lower limbs. METHODS MRI scans showed a dorsal intraspinal extradural cystic

This report is composed of two patients with anteriorly located cervical intradural arachnoid cyst and review of 24 cases in Englishlanguage literature. Both of our patients were in the first two decades of life with neck pain and motor weakness. With suspicious diagnosis of anterior arachnoid cyst

Introduction: Endodermal cysts are congenital benign cystic lesions in the central nervous system and cause various symptoms. Although some have been reported in the posterior fossa, endodermal cysts located dorsal to the brainstem are

Spinal arachnoid cysts (AC) are intraspinal extramedullary loculated cerebral spinal fluid collections. They are relatively uncommon lesions. Spinal AC often cause symptoms such as pain, weakness and radiculopathy. In this pictorial essay we demonstrate the main radiological features of spinal AC,

METHODS A case report of a rare symptomatic, idiopathic, noncommunicating intradural arachnoid cyst (IAC) of the proximal part of the S1 nerve root (NR). OBJECTIVE To discuss the possible pathophysiology, clinical and magnetic resonance imaging (MRI) presentation, intraoperative findings, and

Two cases of congenital spinal arachnoid cysts with paraparesis are presented. Case 1, a 16-year-old male patient, had a 2-year history of progressive weakness of the lower limbs. Postmyelographic axial computed tomography (CT) and myelography revealed a dorsally located extradural mass. The

BACKGROUND Intradural extramedullary cysts are a rare cause of spinal cord compression. We present a case with slowly progressive radicular pain and gait disorder over several years, due to medullary compression by a giant cervico-thoracic arachnoid cyst. METHODS A 65-year-old man presented with

Spinal intradural arachnoid cyst presenting incomplete features of Brown-Séquard syndrome is very rare. Only 6 cases have been reported. We report one in a thoracic lesion. A 42-year-old man noticed thermohypesthesia in his right leg, and monoparesis in his left leg. On admission, he presented

Spinal arachnoid cysts are relatively uncommon an intramedullary location is believed to be extremely rare. A 35 year old woman, admitted with progressive weakness in the lower limbs, was diagnosed as having a thoracic intramedullary arachnoid cyst. After bilateral dorsal root entry zone myelotomy

OBJECTIVE To investigate the impact of endoscope-assisted microsurgical fenestration on temporal arachnoid cysts, and to determine the advantages and limitations of the technique. METHODS Twenty-five children with symptomatic temporal arachnoid cysts were operated via eyebrow supraorbital keyhole
